Perhaps you should try some spelling variations:
"_ optimization algorithm" » "_ optimization algorithms", "_ estimation algorithms", "_ optimized algorithm"
"_ optimisation algorithm" » "_ optimization algorithms", "_ estimation algorithms"
"game estimation algorithm" » "pose estimation algorithm", "game optimization algorithm"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("game estimation algorithm") or ((("_ optimization algorithm") OR ("_ optimisation algorithm"))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("game estimation algorithm") OR ((("_ optimization algorithm") OR ("_ optimisation algorithm")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"game estimation algorithm\") or (((\"_ optimization algorithm\") OR (\"_ optimisation algorithm\"))))".
• Removing quotes may allow a broader search: (( game estimation algorithm ) or ((( _ optimization algorithm ) OR ( _ optimisation algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("game estimation algorithm") or ((("_ optimization algorithm") OR ("_ optimisation algorithm"))))*.
